Step-by-step explanation:

Given :

  • Find the perimeter of an isosceles triangle whose one side is 10 cm greater than each of its equal sides and perimeter is 100 cm.

To Find :

  • The perimeter of an isosceles triangle.

Solution :

Let the length of each of the equal sides be x cm.

Then, length of the unequal side will be (x+10) cm.

‏‏‎ ‎

\bf\green{According \:  to \:  the  \: question,}

Perimeter = 3x + 10 = 100

\implies3x + 10 = 100

\implies 3x = 90

\implies x = 30

∴ The sides are 30 cm, 30 cm & 40 cm.

As we know,

\bf\red{\fbox{Perimeter \:  of \:  a  \: triangle = a + b + c}}

∴ Perimeter = 30 + 30 + 40 = 100 cm.
